Unlocking G codes

[SirDenisNayland]

Hello everyone, I have a little question that I hope someone may be able to answer.

We just put a brand new citizen a20 on our floor which has a 32i control with citizens front end GUI.
There are a number of machine tool macros and "modes" which I know essentially utilize the power of the control in the back end and keep things simple for the programmer.

I was a bit shocked to learn that there are only functions for z1-z2 and c1-c2 superimposition in the machines documented code list. This is a shock because I was hoping I could superimpose y1 into x2 and perform simultaneous front/back boring, yet I've learned they did not include this ability.

Now tinkering through the fanuc manual I have come across g51.6/g50.6 which is a superimposition g code where you select a master and a slave axis using arguments p and q and using the axis is numbers stored in parameter 12600. The code is not in my code list.

Great. Time to mdi test.

G51.6 P101 Q201

"improper g code alarm"

However if I leave out the modifiers I get a ps alarm saying I did not give the correct arguments for the superimposition mode. If I try to cancel with g50.6 q201 it takes the code without issue, and agaib if I leave the modifier out it explains I need one for this function cancel.

From this I get that citizen "blocked" the specific g code and I am wondering if there is a way to unlock this function? It being the superimpose function I know that the z1-z2 superimpose M code the machine has must essentially be using g51.6 behind the scenes.. same goes for the M code to superimpose c1-c2.

There are actually a myriad of functions in the fanuc manual the control is capable of but citizen seems to be hiding them.. it seems they kind of randomly include functions.. its odd to say the least.

Any input would greatly be appreciated.
